Protecting the Fibre Cable ends when not in use.
Protective Cap
When not in use Keynes Controls recommends that a cover/cp be fitted onto the end of
the fibre cable. The cap will keep the end of the fibre clean and so make sure the signal
strength between the instrument and the header unit is maintained at its optimum level
when the cable is re-used.
Protecting the Fibre Cable From Slipping
If a cable gland is used to prevent the fibre cable from moving once
an instrument has been lowered into place. Keynes Controls recommends the fitting of a number of Star Washers onto the cable as
shown opposite above the gland.

amount of excess cable to make termination in a
appropriate place and allow for repairs should the
end of the cable become damaged.
